To all whom it mrlfylooncer:

Beit known that I, WILLIAM F. LAUTEN- SGHLAGER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Punching- Machines, of which thefollowing is a speci ication..

My invention relates to punching-ma- 1ochines, especially adapt-ed for providing the punchines. upon boot or shoe'uppers, harness, saddlery goods, and for similarpurposes, and has for its object the providing in a machine of this character of novel punch- 1 5 operating mechanism, of means for determining and ga' ing the .cross reciprocating of the punch, o novel means for providing a traveling cushion adapted to receive the impact of the cutting edges of the punch after zo piercing the material, and the ,providing of new and :improved means for feeding stock, whereby the punching and otherl operations applica le for producing imitation tip-vaip's for boots, shoes, slippers, and the like are a'c- 2 5 complished, and for similar operations; and the invention will be readily understoodfrom the following description and claims and from the drawings,lin which latter- Figure 1 is a front elevation of lny ini- 3o proveddevice'with its cam end broken away.

Fig; 14 is a plan view of p Fig. 15 is a plan view of the the stock-guide. base of the same. Fig. 16 is a planview of the shifting-bar ofthe same.' Fig. 17 is a detail showing a shoe-feed and Fig.- 18 is a plan view' of a section of .the cushion-strip, show-4v ing the punch-marks thereon.

1 represents the frame of the machine, in i which a driving-shaft 2 is journaled in bearings 3. The driving-shaft may be operated in suitable `manner, as from a pulley 4. A

cam 5 lfor reciprocating the punch-ram up and down is mounted on the driving 'shaft. The driving-shaft may also carry a cam 6 for reciprocating the punch-ram head back and fort 1.l

A cam-block 11 takes about the cam 5 and has contact-faces 12 13, with which the cam 5 engages. The cam-block also has a slot 14, the Walls of which take against the shaft 2 during rcciprocalion of the cam-block. The

cam-block has a link 15, which has articulation with a crank-arm 16, as by connecting withA -the same by meansof pin 17. The crank-arm 16 is secured to a rock-shaft 18, journaled in` bearings 19 in the frame and carrying a crank 20, on which there is a crankpin 21, having journal connection with a slide-block 22, reciprocating in slideway 23 of an operating-block 24, secured in manner hereinafter described to the-punch-ranf25 for reciprocating. the punch-ram and l down for performing the punching operation.

The punch-ram is mounted onV a punch-l' ram head 30 in bearings 31. This punchram head is preferably supported on rods 32 33, secured 1n bearings 34 l35 of the frame,`

about which respective rods bearings 36 37 on 'the punch-ram head rcspcctvely take, vthe unch-ramhead preferably reciprocating bac and forth `upon said' rods in manner hereinafter desclibed.

A cani-block 41 takes about the cam 6 for being operated thereby. LIt has cam contact-faces 42 43. This cam-block is'pivoted on a rock-shaft 44, journaled in bearings 45 in the frame, and carriesan arm 46, which the rock-shaftv and communicates its `motion to the punch-ram', preferably by'provid ing the punch-ram head with a slot 47, the armv 46 having 'a T-slot48, in which a T-bolt 49' is adjustably placed. Thehead of the bolt 49 takes-to inside the walls 5() of the slot 48, a washer 51- aking lIO againstthc outer faces ofsaid walls, aleeve A -52 taking about said bolt against saldwas'her,

l i l l l s l i l l l i ar1fi46. The bolt 4!) andparis carlied thereplatel 54 by are permitted longitudinal movement wil h relation to ihoslois, respeta ively, in the arm 46 and in the punch-ram head for imparting reciproca'l ions l'oi different lengths 1.o the punch-ram head., Thus the nearer the bolt is secured iocitrd therocking axis oi the rock-Shah 44 tlhe less will be'lhe length of stroke of crpss i'eciproi-,aiion of the purchram head, and [he farlher from said axis the articulating means belween.s aidv arm and' rock-shaft are located the greai er will bc the length of stroke of'said cross reciprocation. i

A slight movement between the articulating means and one of' said slois is permitted after adjustment, owing to the fact that the arm 46 swings along an arc while the cresstravel' of the punch-ram head is alongholi-V zontal lines. Adjacent the {sloi 48 theref is 'a seale or age 56, a finger57 being on\th e or registering witht'he markings of said gage in order tolocai'efihe articulating connection., along said gage, and' thereby im. part desired length -of crcssfreciprocaiion io. the punch-ram head'. fi The punchings made -with a machine 'of this character' are'of diil'crent lengths, .andV the feed is desired io be 'of Vthe requisite length to properly space ihe various punchngs. Thus some punche'sgi require a vex'v small length of'feed. Othelii requirea maximum lengthof feed. I desire to divide ihe scaleI int o degrees oi' given numbers represent-V v ing the' given travels `of feed and recorre.-

.obtained spondingly mark'the punches, cso that the operator up'onseeing the"nu-mber of the punchl may ai once know that if the finger is set to aeorres'ponding nui" ier on the. ga e the correct cross` travel ofjgifhefeed will lie In the form shown the punch-ram preferably comprises a-casing 61, movable u and down in the bearings 31 onjthe 'princi-ram head. A punch-ram shank 62 has a punchv head 63, having a socket 64forrecelvng a punch 65, and for locating the pkmching part 66 correctly abou-t the longitudinal axis of the punch-ram I provide the headavith a in 67, taking into a slot 68 in the punch. he punch-shank is preferably permitted to rock with relation to the casing, as by haging ball- 'bearing 69 between the giunch-headiv and the casing, the end .o the shank being threaded, as shown at 71, for receiving set' nut 72and lock-nut 7 3 ,a.washer 74 being interposed between the setfnut and end ofthe casing. This construction permits adjustv ment of the roekingbear ing ofathe .part 66 1s preferably coincident with the the head the operating-block 24 is provided witha clamping member 75^about an interJ nally-threaded bore 76, taking about the ou'ter threaded face 77 of the casing. 'lurntion to the operating-block for bringing the cuttingfface of the punch closer to or farther from the top plane of the-table, the table being shown 'at 78. A set-screw 79 preventing turning of the bloc relativelyY to the punch-ram head said head is provided Vith a plate 80 vtaking into a slot 81 in said vprefera ly V-shaped recess 85, thevwalls of which are adapted to enga e acorrespondingly-shaped finger 86, the s ank 87 of which is mounted vin a bracket 88, secured to the the shank' and the bracket, suitable means ger and nuts 90 91 limiting the outward movement ofthe finger.` The punch-ram is 'said gage.

A-pressure-foot .101"s mounted on va rod frame, a sprin 104 taking against the upper end of the roi and being seated in a recess '105' in upper bearing 103. A bolt 106 has a recess 107 for receiving' the upper endl of the'.

e `frame for adjusting the tension of the spring. 'lhe rod has a bracket 1 11 ladjust- 'a ly secured thereto, as by a set-screw 112, the crank 20 having a finger 113 thereon takforautomatically raising the pressure-foot. 101 during operation of the machine. The bracket has an extension 115, under 'which a finger-1 16-is arranged to take for manually mounted on a rock-shaft 117, having an arm 118 secured thereto, towhich a .link 119 con- -e'rating the spring 120 takingabout the link'against the arm 118 for aiding in automatically return` inglthe pressure-foot into depressed position,

The forward or initial part of the punching rocking 'axis of the punch, the major part of the punch being to rear of said axis.' fFor adjusting the punch-ram longitudinally in 7o .being provided. to vprevent turning of the inalso provided Withfst'ems 92 93, adapted to 95 head for limiting the'rockin motionnf the mich-remand preventing t e recess-85 be- .mg thrown out of range 4withvtlie nger 86. V.A stock-gageis adjustably and releasabhi ioo secured to the frame, as by having a set-screw 96 take into theframe through a slot 97 in nec'ts, the link preferably extending 'below the frame of the machine into suitable position for carrying a suitable'foot-plate for op- :25:

pressure-foot with the foot, ik

ini; the casing raises or lowers the same with 7 5 Y re a vlocks the parts in adjusted osition.' For 8cv Thel unch-ram shank is provided with a v85 frame, a spring 89 taking between the end of 9o 102, reciprocating in bearings 103 in the io 5 spring and has threaded connection 108'with i i o t ing against a shoulder 1 14 on the bracket 11 1 1 x 5 raising the pressure-foot, the finger 1 16 being i 2c desired to raise the pressure-foot by hand. In the construction described the punch is given a crossreciprocation for feeding the material anda reciproeation up and down for performing the punching function.

4In order to provide a clean-cut'punching or perforation by thev punch and to save wear 'u on the cutting-faees of the punch, I puo? vlde a traveling cushion toreee1ve the iinal im act ofthe cutting-faces ,of the punch. In or er to eeonomize 1n the amount of cushron employed, I give this cushion only .a slight.

feed with relation to the feed ofthe stock bcing operated upon. Thus 12'1 represents a strip of his. cushion, which in practice is softer than metal an'd of such material as not to injure the punch and is preferably a narrow strip of paper fed to the machine from -a suitable roll mountedon a suitable stud of table for permitting insertion'of the c ufslu'on'-v strip.

126 1s a.stripguide,preierably com rising v a plate 127,-seeured to the'bottom oft e ma-f chine-table and provided rwith. slots 1,28 of different lengths -to accommodate 'dierent i widths of' the cushionstrip; The 'eushion.

strip then passes throu h a slot 129 in the ta` ble and over a bedfbloe 130, which islocate'd under the punch and is referably'of hard material, as hardened stee ,and forms' an ,an-

vil for backing up the.cushionstrip. "Thei cushion-strip then passes through a slot 1314 4in the table nd a strip-guide 132, similar to the strip-'gu' e 126, the-strip-guidcs at front and rear of the anvil guiding the strip in correct alinemerit with relation to the unch.

vThe strip is then operated on bvvfeeding device 135. In the form shown t lis comprises a feed-shaft 136, having on it a feed-wheel v137, which is preferably a toothed wheelen-A gaging the feed-strip 4and so arranged that its contact with the latter communicates its motion te said strip, the cushion-strip preferably passing between the feed-wheel and an impaetpart 138 ofthe table. The feedshaft is ]ournaled in bearings 139. For operating the feed-shaft in the form shown it'is rovided with a ratchet-wheel" 141. t aid ratchet-wheel is operated from a rocker-arm 142, shown a's secured to the rock-shaft 44 and having a link 143 articulated tlmrewith in adjustablepOstin'thereon. vThus the rocker-arm is rovided with a slot 144. A

stud 145 is sli able in'said slot and secured therein insuitable positions by means of a nut 146, the link 143 having a bearing 147 about ratchet connection with the ratchet-wheel said' stud. The lower end of the link 141i, as by having aratchet-housing 14 8rpek' i ing upon the feed-shaft 136, articulated with j the link by means of astud 149 and provided .70

4with ratchets, 150, the said ratchets being spring-pressed toward the ratchet-wheel by meansof springs 151' in slots 152 of said hous. ingand alternately engaging said teeth. .A

I' late 153 holds the ratchets invsaid slots.

' Vhile one ratchet engages a given tooth the etherratchet is riding upon another tooth,

and vice versa, for permitting the teeth to be g made coarser and stronger than if only one ratchet were employed.` The nearer the stud 8c:Y

145 is placed to the rocking axis of the shaft 44 the less will be the motion of the ratchethousing 148, andeonsequently the less will be the 'circumferential travel of the feed-wheel,

`whereas the farther the stud 145 is placed 'away from 4the rocking axis of the rock-shaft 44 the greater will be the" circumferential vtravel of the feeding-surface of sadfeed 'wheel and the 'consequent feed of the cushionstri The'relationsofparts are such that ed to the feed-strip than the distance of cro'sslfeed of the' stock, and While the punehin s upon the'stock follow one another the -pune 'marksu on the cushion-strip need .be relajtively a vanced onlyT substantially the .dis-

tance of the width of a single cutting edge of the punch-tube, which in practice is very slight, and the relative travel of the stock with relation to the travel of the `cushion, roo

strip may be only, for example, the ratio of one inch or less travel in the cushion-stri to the't'ravel of one foot inthe steek, thuse ecting a materialsaving in` the amount ofi-cushion-strip employed. In Fig. 18', for instance, 1o 5 I have shown the relative impressions left u on the cushion-stri .bythe punch, from w 'ch it will be seen t at' successive imp resf 'sions by the punch upon the cushion-strip overlap each other, while by reference to Fig. 1 i o 14y it Will be seen that the successive impressions upon the stock are wholly in advance of one another. y

The cushion-strip 1npractice may be a strip of comparatively thin paper-say of one- 1 I 5 hundredth of an inch in thickness==end is es`- pecially useful inaY umh-feedingpunching- ,machine of the clliaracter of that herein shown and described, as the rearward crossfeed of the 'punch takes place while `the 12o puneh points or tubes 'pre embedded in the stock after land during a slight 'rise in the punch., the.- eushion-strip insuring that such embedding -shall be definitely effected, so

that the punch may carry the stock with it 125 in its rearward cross recrprocation without fail. Thus the relation ofthe rock-shaft 18 to the crank-pin 21 is such that at its initial descent the punch-'ram is forced downwardly to its f ull extentr when the crank-pin 21 is 13o i i i Y 9 i pre erably an apprceiably less feed 1s 1mpart' vertically under the rocking axis of the rockl button 180 for raising. or' moving the same.

The clampv has lugs 181, arranged totakeV4 against the side faces of the bar partd70 of.'

shaft 18, the rock-shaft, however, continuing.

its rocking motion slightly beyond this center in order to slightlylraise the crank-pin, and thereby slightly raise the punch suiiiciently, preferably to allow it tev clear the cushion-strip in itsrearward crosswise travel, while, however, beingv still embedded in the stock for feedi G the stock in such crosstravel, the slidelock 22 remaining stationary in such slightl y'raised' position during said rearward cross travel of the punch which now `takes place for vperforming* its feeding function. The crank-pin then' rerocks in reverse direction past its lowerniost position for raising the punch' out of the stock, the can 6 then cansino' retraversing of the punch-ram'head forwardly to initial position. The pressure-foot andits connections are so'tinied that the'pressure-foot contacts the stock from the en'd of the feeding operation until the punching operationv takes place. In the meantime if imitation tip-Vamps are being punched or similar operatioris performed the stock is being swung about its pivotal support in the manner now to b e described. f

-161 is a stock-guide especially ap licable for use in punching 'or performing ot er operatioris on imitation tip-Vamps and for of said punehings vconcentric therewith they are provided with a row of stitching to imitate the stitching in genuine tip-Vamps,

ace

false strip of suitable material being p under the punchings for hiding the inner lining of the shoe.v The 4punching is per.

formed by the reciprocating tool herein i shown, as the punch andthe sewing upon this and other similar work is performed by 1' the reciprocating tool exemplified as a needle.'

The stockguide comprisesa base-'162, swinging upon 'a pivot 163, mounted ona 'b ai' 164, adjustably attached to vthe table 18 of the machin as by having a slot 166, through which a be t 167 on the table takes, a nut 168 takingmver the b olt and clamiping the bar 164'in adjusted positions to t tures 169, into any of which the pivot 163 is arranged to take. The base preferably com# prises a Arearwardly'-extending' bar' 170, 'in which the apertures 169 are provided, and a widened stockysup ortingplatenll. VThis platen is prefere, y very thin, s'o that the 'stock represented at 172, showing an imita- 'of the ta le-top.

is a clamp which has a rearwardly-ex- .tending bar 17 6 and a widened clamping part "-177, preferably comprising side extensions table. The base is provided with a series of aper-..i

the base, and has a finger 182, arranged te take into a depression 183 in the base For positioning the clamp. A bolt 184 projects from the base through a slot 185 in theclamp, a spring 186 normallyr forcing the clamp toward the base. A washer 187 may be interposed between the spring and clamp and a nut 188 provided for adjusting thetension of the spring. Preferably the reciprocating tool end only of the clamp takes against the stock, as shown by the bend 189`in' the clamp.

In practice the vamp or other stock before being operated o n by the reciprocating tool 'is rovidedwith small points or marks (indicafped at 191) to indicate' to the operator the distance from the outer end of4 the stock Aend 193 of the slot 185 against `the bolt 184:.`

The stock is then adjusted so that the points 191 will be substantially' coincident 'with the inner face of the are connectionV 179,' which brin the stock into correct relation to the vertical plane of'thereciprocatingvtool to re- 'f"ceive the Same in ro er osition. The clam 175 is then raise 'whi e the stock is held in position' and shifted for bringing the inner end of slot 185 against the bolt 184 and then released, thereby holding the stock in position for receiving its operations and out of the Way or range-of the .action of the re- IOC 'ciprocating too`l. The stock and baseare swung upon the pivot 163 'for bringing the Vstock into roper position for receiving the o erations y the reciprocating tool, the mac 'ne automatically feeding the stock about the pivot v163 until thev operation is comleted, whereupon the stock is released and a csh piece inserted for repeati the operation. Inraising or moving th; clamp 'the o erator usuall rests the pall o h'is hand on t nut- 188 w 'le mani ulating the button with his thumb and gers, thereby pre- .-ventingdisplacement of the base off its pivot; but, if desired, the pivot may have a retainingscrew' .195, whose head takes into recesses 196 adjacent to thea ertures 169, {erpre- ,venting accidental disp aceinent of the base, and the bar 176 may have a slot 197 for convenience in gett' at the screw 195. In setting the-stock-gu1de' the diameter of circle upon which the o ation is to be performed by the reciprocating tool is rst determined, this' circle varying with diiierent size and IIC style of vanips or other work. Each of the apertures 169 represents 'a center of dijorent circle of swing.l Thus the Ainner apartunV mnrePreSentehiPWee-mch-diciem.

Massa 'i 5 outer aperture a twenty-inch circle, the other.;

apertures representing intermediate circles, or theapertures may have any other value or there may be any number of apertures.

Assuming' now-.that it is desiredv to punch.

upon' a fifteen-inch circle, the machine having previously been set to punch u on a different circle, the nut 168 is relieve for permittingshifting of the bar 164, the base-` piece is raised away from the pivot and again placed vabout the pivot, with the third aperture from the inner end of the series o f a ertures registering. with-the pivot. The c amp is then slid `inwardly for ca'usinggthe outer end 193 of the slot 185 to contact the bolt 18.4. The vamp to be punchedi's then laced under the punch in proper position or receiving the punches on the correct line and the inner. edget of the clamp caused to register with the points 191- upon the vamp. The nutv 168 is then turned and slotted bar 164 clamped to the table, thereby positioning the vbase and clampforsubsequent operations, and the clampfslid back out of range of the punch a sufficient distance preferably to also accommodate the pressure-foot between the punch and the clamp. The inner end of the clamp is preferably on the arc of the smallest circle accommodated by the swinging base. A

In the` construction shown the punch in feeding rocks upon its rotary axis and is autornaiically returned to initial position'at the beginning of-lthe punching stroke. As

-the punch-ram moves rearwardly for feeding the stock it swings the'varnp upon the pivot 163 and at the same time'roclrs about its 'rotary axis for accommodating changing positions of the holesii'n the vamp during its swing, it being understood that duringl such rearward reci rocationsfofvthe punch for performing the ceding-, action the punch-ram does its traveling in ajstraigltt line, (indicated bv the line 'wlw in Fig-.14 the punch-ramal'so rock-ing slightly uponjits rotary axis. In order to ap roximatejit'his rotary shifting of the punch i ue to tlieswinging of theclamp as near! as possible with the right line of travel o lthe punch-ram head, I mount the pivot 163 to one 'side-that is, in rear of the lateralplane in which the initial or toe part .of the unehing'part of the 'punch is located while r eseending for performingv its punching function. 'thus in l"ig. 14 the dotted line a: represents the lateral plane in which the initial or toc part of the punching part of the punch moves in its desccntfor -performing the punching" action, and the dotted line y represents the lateral plane of the pivot 163.

I have found that an. advisable distance bel tween these lateral planes is one-fourth inch for usual work in punching Vamps, although it is of course readily undors. ood that I do not restrict my invemion to any particular distance. ln this manner it will be noted known manner, the fee that the distance of feeding action in the eX- ample of punching shown in the drawings is represented by the distance between the respeci-ive vtoes 198 of the respective unehings 199`on the vamp 172 and that the eed of the punching just performed will be from the line representing the lateral plane of the beginningof the feeding operation, to the line p z, representing the lateral plane of the ending of that feeding operation, the lines :r z vrepresenting the'limits of the feeding operation, and'that the pivot 163 is' located in a lateral plane intermediate of'tzhelimits of feeding action of the punch-that is, said lai eral plane is between the beginning and the end of the feedin action for the punching just performe -.-and this is preferably the lease whether the feeding action is performed by the punch itself or by an ordinary feedingshoe, the strain uponthe stock during said feeding action being thereby reduced to the minimum.

In FigE 17 I'have shown an ordinary shoefeed, in which 200 represents the feedingblock, reeiproeated in an ordinary or wellding block or shoe usually having an upper roughened surface for contacting against the under face of the.

stock, a pressure-foot operated in suitable manner taking against the stock above the feeding-block andmoving rearwardly with itlforcausing impingement of the stock against the'block for feeding vthe stock. In this exempliication y represents the lateral plane ofthe rocking axisof pivot'163. a represents the beginning, and z the ending, of the feeding stroke;
